ʻO ka Hydroxypropyl methylcellulose he ether non-ionic cellulose i hana ʻia mai ka cellulose material polymer maoli ma o nā kaʻina hana kemika.He ʻano mea ʻala ʻole, ʻala ʻole, pauka keʻokeʻo ʻawaʻawa ʻole, e pehu ana i ka wai anuanu a kapa ʻia ʻo ia ka solution colloidal a i ʻole ke ao.Loaʻa iā ia nā waiwai o ka mānoanoa, hoʻopaʻa, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, mālama i ka moisture a me ka pale ʻana i ka colloid.
Hiki i ka hydroxypropyl methylcellulose maikaʻi ke hoʻoponopono i ka pilikia o ka paʻa ʻana o ka wai ma lalo o ka wela kiʻekiʻe.I nā kau wela kiʻekiʻe, ʻoi aku ka maikaʻi ma nā wahi wela a maloʻo a me ka hana ʻana i nā ʻāpana lahilahi ma ka ʻaoʻao o ka lā, pono ka HPMC hydroxypropyl methylcellulose kiʻekiʻe e hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka slurry.
ʻO ka hydroxypropyl methylcellulose kūlana kiʻekiʻe he kūlike maikaʻi loa.Hoʻokaʻawale ʻia kāna mau pūʻulu methoxy a me hydroxypropoxy ma ke kaulahao molekula cellulose, hiki ke hoʻonui i nā ʻātoma oxygen ma ka hydroxyl a me ka ether bond a me ka hui wai.ʻO ka hiki ke hoʻohui a hana i nā paʻa hydrogen e hoʻohuli i ka wai manuahi i wai paʻa, a laila e hoʻomalu pono i ka hoʻoheheʻe ʻana o ka wai i hoʻokumu ʻia e ka wela wela a loaʻa ka paʻa wai kiʻekiʻe.
